Is this a regression from Plasma 5.24? Can you reproduce the issue on X11 too, or just Wayland? (In reply to Nate Graham from comment #1) > Is this a regression from Plasma 5.24?

On X11, there has been pixelated artefacts on the screen in Plasma 5.24, but on Wayland on Plasma 5.24, there was none, so for Wayland, it is a regression. Thanks. Cannot reproduce with an Intel HD620 iGPU, FWIW. Created attachment 149221 [details]

I have the same issue on almost the same CPU/GPU but It's not a regression, it's been here some time. Could it be Bug 316734? I can reproduce Bug 316734, but I don't see any pixelated artifacts, just the desktop itself for a moment before the screen locker screen appears.

That bug, if I read it correctly, is about lock screen not showing soon enough and desktop being temporarily fully visible. But in this case instead of the desktop being fully visible there is a random mess of pixels that slightly resembles a combination of the lockscreen and whatever was on the desktop previously. That said, these two issues likely have the same root cause. Can reproduce on an old HP Sleekbook 14 (old AMD APU, using radeon driver). It's been happening ever since I moved to Plasma a few months ago. The artifacts I get are way worse, I barely can see anything except for the cursor, which is rendered correctly. However, apps are still running (I can see the color changing if I close a Chromium tab, for example). I tried disabling screen lock on suspend but it keeps happening, so likely kscreenlocker is not the culprit (tried uninstalling Latte dock as well, same results) Arch Linux user running on Wayland, packages updated, so similar setup as the OP. It's not happening on Sway, or cage, so it seems to be a Plasma issue. Glad to help if you need more info/logs/etc I also can reproduce it on my Acer Aspire V5-552G. There isn't any problem with X11, but it happens on Wayland. Distro: Manjaro Linux (stable branch), kernel 5.15.41-1; graphics: AMD Radeon HD 8650G (iGPU); driver: radeon; Plasma version: 5.24.5, KF version: 5.94.0 I think this bug is probably a duplicate of https://bugs.kde.org/show_bug.cgi?id=316734 *** This bug has been marked as a duplicate of bug 316734 *** Same problem only on Wayland, no problem with X11.
